Cisco at $112: The AI Growth Story Is Real, But the Stock Isn't Cheap

Cisco reported its best fiscal year on record. Revenue hit $63.3 billion, up 12% — with the fourth quarter alone posting $17.3 billion, up 18% as networking product orders surged 40%. The company guided fiscal 2027 revenue to between $72.2 billion and $73.4 billion, well above Wall Street's $68.7 billion estimate.

The stock fell more than 9% in early trading.

The headline claim chasing Cisco is that it trades below fair value while AI demand builds. That sounds right until you check the numbers. At its current price of roughly $112, Cisco carries a forward P/E of roughly 43x and an EV/EBITDA multiple of 25x. Morningstar, one of the more vocal supporters, recently set its fair value estimate at $115 — three dollars above a stock that has surged more than 60% this year.

There is no crack here. The market hasn't missed the story. The question is whether the story can sustain the price.

The AI angle is real. Cisco generated $4 billion in AI infrastructure revenue in fiscal 2026 and says that figure will jump to roughly $7.5 billion next fiscal year. That comes from hyperscaler orders for its Silicon One switching systems and Acacia optics — the pipes and interconnects that hold AI data centers together. Full-year AI infrastructure orders reached $9.3 billion in fiscal 2026, roughly 4.5 times the prior year.

Cisco is not building AI chips. It builds the network fabric that connects them. And hyperscalers need that fabric to scale.

Beyond hyperscalers, a multi-year campus networking refresh cycle is underway. Campus orders grew 20% in the latest quarter, and Cisco says its next-generation portfolio is ramping faster than prior launches. Security and observability — areas where Cisco has acquired companies to strengthen its position — are expected to move from low-single-digit to high-single-digit growth next year.

The operating leverage is striking. Non-GAAP operating margin reached 35.9% in the fourth quarter. For a company of Cisco's size, that is not incremental improvement — it is a structural shift. Operating expenses grew only 5% year over year while revenue jumped 18%. The company achieved what it called its highest productivity metrics in 30 years.

Revenue growth of 12% for the full year, with guidance implying roughly 15% next year, is not what investors typically associate with a legacy networking company. Cisco is no longer the slow-growth dividend stock it was a decade ago. The business is turning up.

Here is where the cash flow work matters.

Cisco generated $14.2 billion in operating cash flow over the trailing twelve months, with free cash flow of $12.8 billion after $1.4 billion in capital expenditures. That works out to a free cash flow margin of roughly 20% — up from 17% two years ago, then declining slightly as revenue volumes have accelerated and inventory has built.

Inventory is the first red flag in the plumbing. Cisco's inventory balance has nearly doubled over the past year, climbing from roughly $2.8 billion to $5.7 billion. That is what happens when you are building to order surges — you stockpile components ahead of production. It is not necessarily a problem, but it is working capital that hasn't turned into revenue yet. If the demand pace slows, that inventory is a drag.

Free cash flow growth has been negative year over year at roughly minus 4%, even as revenue grew 12%. The divergence is driven by inventory build and a $1 billion restructuring charge that the company announced in May. That charge reflects real costs of pivoting engineering toward silicon, optics, security, and AI — but it is also a reminder that transformation is not free.

Debt has climbed from roughly $55 billion two years ago to $79 billion today. Net debt sits at $13.6 billion after accounting for $7.2 billion in cash. Debt-to-equity is 0.59, well within comfort, but the upward trajectory is worth tracking. Cisco uses debt to fund buybacks — roughly $8 billion in repurchases remain authorized with no termination date. That is shareholder-friendly in a rising market. It is also leverage that sits on the balance sheet whether the networking cycle bends up or down.

The dividend tells a steadier story. Cisco raised its quarterly dividend to $0.42 per share, marking the 15th consecutive year of increases. The payout ratio sits at roughly 55% of earnings, and free cash flow covers the total dividend bill by a comfortable margin. The distribution is safe. The yield of roughly 1.5% is modest but reliable.

Now let's talk about what the multiples actually say.

On a trailing basis, Cisco trades at 33x earnings and 25x EV/EBITDA. On a forward basis, using the midpoint of the $5.05-to-$5.11 EPS guidance, the forward P/E stretches to roughly 43x. Those are not the multiples of a forgotten legacy hardware company. They are the multiples of a growth story the market already owns.

The peer comparison doesn't help the "below fair value" claim either. NetApp — a storage company that is not a direct Cisco peer but trades in adjacent enterprise infrastructure — runs at a trailing P/E of 28x and EV/EBITDA of 19x. Cisco's multiples are meaningfully higher on every measure. The stock has not been left behind by its peers. It has pulled ahead.

The PEG ratio — P/E divided by earnings growth — sits at roughly 1.1. By strict value-investing standards, anything above 1.0 is not cheap. It is fair, assuming the guided growth actually materializes.

Morningstar's fair value estimate of $115 implies roughly 3% upside from current levels. A select-group DCF analysis on Simply Wall St suggested 28% undervaluation, but DCF models on high-growth companies are highly sensitive to the terminal rate and assumed growth horizon. A small change in either assumption wipes out the headline conclusion.

The analyst consensus price target of roughly $130 implies about 16% upside. That is a reasonable target if Cisco delivers on its guidance and the multiple holds. It is not a margin of safety.

This is where the contrarian reading comes in.

The article you saw — the one claiming Cisco trades below fair value as AI demand builds — is not wrong about the demand. It is wrong about the valuation gap. Cisco's operating performance is the strongest it has been in decades. Revenue is growing. Margins are expanding. AI orders are accelerating. The business is executing.

But the stock price has front-run every one of those developments. It has risen 68% in the past year precisely because the same investors reading those earnings releases were buying into the AI networking narrative months ago. The 9% sell-off after the latest earnings beat is textbook: when expectations are already sky-high, even a beat feels like confirmation rather than surprise.

For a value investor, the entry point is the crack between what the market prices and what the cash flows support. That crack does not exist at $112. It existed at $66, where Cisco traded roughly 18 months ago on a P/E below 20, before the AI order acceleration became visible. Investors who bought there have more than doubled their money. The question for a new entrant is different: can this stock still grow its way to a higher multiple, or does the risk-reward tilt toward the downside if growth decelerates even slightly?

Cisco's own guidance implies roughly 15% revenue growth and 17% earnings growth in fiscal 2027. The core business — excluding the $7.5 billion in AI revenue — is expected to grow roughly 10%. That is solid. It is not explosive. And a 10% core growth rate at a 43x forward P/E demands that the core keeps growing at that pace for years. One quarter of softness in campus refresh or a pullback in hyperscaler capex would compress the multiple quickly.

Analysts noted after the earnings release that the outlook implies lower product gross margins going forward — a form of margin dilution as lower-margin AI hardware mixes into the revenue base. AI hardware is lower-margin than Cisco's traditional enterprise networking. If the AI revenue share grows from roughly 6% of sales today toward 20% by the end of the decade, as Morningstar projects, those margins will come down. The operating leverage story depends on volume offsetting margin compression. That is a real execution risk.

All things considered, Cisco is a company with a genuine second act playing out in front of investors. The AI networking opportunity is material. The execution has been strong. The balance sheet is manageable, and the dividend is safe.

But it is not below fair value. The valuation reflects a market that has already absorbed the AI growth narrative and priced it in aggressively. At roughly 43x forward earnings, there is no margin of safety — only a bet that growth sustains and the multiple doesn't contract.

For an investor looking at Cisco today, the holding case is stronger than the buying case. Existing shareholders who bought below $80 are riding a wave that has not broken. New buyers at $112 need the AI revenue story to deliver $7.5 billion next year, then grow toward $20 billion by decade's end, and they need the core business to keep growing at 10% — all without a meaningful multiple contraction. That is not impossible. It is not cheap.

The margin of safety is the difference between a good business and a good investment. Cisco is the former. At current levels, it is not yet the latter.
